Pls Help me cook beef joint in slow cooker- am not a natural cook!!

I have bought a beef joint (rolled brisket) .83kg (about size of very big grapefruit).

Want to cook it whole in my slow cooker (think its a 6.5L- joint looks rather small now!). I have been inspired by reading about other MNers melt in the mouth beef joints!!

Can anyone give me an idiots guide as to what setting, how long, and how much liquid and any other ideas like maybe adding some veg (have carrots, parsnips and potatoes).

The recipe book that came wth the slow cooker suggests covering the meat and veg in liquid, simmering for 5 min then adding all into cooker including all the water- but having read some threads on here I don't think that sounds like the best thing to do.

slow cookers are very forgiving - they work on the sling it all in style of cooking! If I have a lump of beef I just put it in and add say a cupful or liquid - stock, or beer, or wine. you could add other things - onions, garlic, carrots, celery, herbs, mushrooms - chopped- for flavour. maybe teaspoon of mustard for oomph. i don't add pots as they don't tend to cook - stay hard and never tried parsnips so dont know. tin of chopped toms maybe

not sure about your settings - i have high/low/auto. if you only have say 4 hours ish then you probably need to use high, if its more 8 hours ish then low. auto starts off as high and then once going nicely reduces to low.

you need to add much less liquid than you would in the oven. if it looks too liquidy towards the end, either tip some out or add gravy granules or flour mixed with some cold water. if i was doing a joint i could get away with couple of eggcup fulls of liquid - though i normally add more so i don't have to bother with gravy

i don't bother with simmering first or browning - too much like hard work - and no-one every complains.

i cook my roast beef joint in mine every week! i just chuck mine in at 9am with seasoning and drizzle of olive oil at 9am and leave it on until when re ready 2 eat! the brisket cooks really well, i also do my lamb in it!

I've brought a joint of beef for Sunday dinner but I want to cook it in my slow cooker how long does everyone think i should cook it for on low, my partner leaves for work at 8am and finishes around 5.30 so would like it ready for when he gets home what would be the ideal time to do it in?

At around 8/9 am I usually brown whatever joint it is in the slow cooker pot and add a glass of wine or beer and the same of stock plus onions, carrots, leeks, celery and herbs. Bring it to the boil on the hob then cook on medium until ready to eat. I take the meat out to rest and carve then blend the liquid and veg with a couple of spoonfuls of flour, I seive it , taste for seasoning then bring back to the boil on the hob.
